Saturated Dissolved Oxygen Concentration in in situ Fragmentation Bioleaching of Copper Sulfide Ores

Frontiers in Microbiology, 2022
In situ fragmentation bioleaching is a promising way to perform deep mining safely, economically, and in an environmentally friendly manner, where oxygen plays a critical role in microbial growth and mineral dissolution.

An Enhanced Naive Bayes Model for Dissolved Oxygen Forecasting in Shellfish Aquaculture

IEEE Access, 2020
It is difficult to predict dissolved oxygen values because they are disordered and nonlinear. Accurate prediction of dissolved oxygen in shellfish aquaculture plays an important role in improving shellfish production, and a reliable model is needed to ...

Modeling the Effects of Algal Bloom on Dissolved Oxygen in Eutrophic Water Bodies

Journal of Mathematics, 2023
Algal blooms have a wide variety of detrimental effects on both the aquatic environment and human activities unfortunately, including a decrease in dissolved oxygen levels in water.

Control of condensate dissolved oxygen in steam surface condenser. Reconstruction experience

Results in Engineering, 2022
Dissolved oxygen concentration in the steam turbine condenser significantly influences the failure-free operation of the power unit.Despite the wide range of recommendations and operating experience, there are still condenser working regimes with ...

The impacts of physical processes on oxygen variations in the North Sea-Baltic Sea transition zone [PDF]

Ocean Science, 2012
The bottom water of the North Sea–Baltic Sea transition zone suffers from seasonal hypoxia, usually during late summer and autumn. These hypoxic events are critical for the benthic ecosystems and the concentration of dissolved oxygen is an important ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dissolved Oxygen Balance Model for Neris

Nonlinear Analysis, 2001
We consider a dissolved oxygen balance model for Neris, which includes biochemical oxygen demand, nitrification, sedimentation, algae respiration and photosynthesis. The load from point sources, tributaries and distributed sources are taken into account.
